RBS Glue resistance increase weeks after weeks
Because of the perfect "symbiosis" with the sail-cloth,
( similar flexion modulus, similar dilatation, similar thickness ),
Age, Stress and Folding increase the stressmap homogeneity in the seam.
RBS M5 performance increase ( in opposite sail-cloth performance decrease ).
This explains the best durability years after years.
To understand why

POLURETHANES REACTIVE HOT MELT SYSTEMS (PUR):

 We can see here schematically what has to be done to produce reactive hot melts;

The  sequence shows us the production of a polyurethane hot melt with terminal MDI isocyanate ( 2 to 5 %) groups in the polymer chain.
Under the impact of humidity these isocyanate groups are cross-linked to polyurea.
As a large number of diols and multifunctional isocyanates is available, there are many possibilities for variations and modifications, and - at least from a chemist's point of view. 

Now, where does the reaction partner - that is humidity - come from ?

After the bonding process, humidity will hardly be able to penetrate into the adhesive film. But every substrate is provided with an invisible humidity film which as a reaction partner may set off the reaction.
These traces of humidity alone are already sufficient for the reaction mechanism, and they are practically always present. In many cases, the substrates to be bonded additionally contain reactive OH-groups which may induce the reaction; this is the case with wood materials."
